Example

The follwing example will make even numbered bitmap items in the animation wait for user input, and then reads the new state for each item in the bitmap list.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT LAnimationWindow_WaitForUserInputExample(HWND hWndParent) 
{ 
   L_INT nRet; 
   L_UINT i; 
   LBase::LoadLibraries(LT_ALL_LEADLIB); 
   //make sure all libraries are loaded 
   LAnimationWindow MyAnimation; 
   MyAnimation.SetFileName(MAKE_IMAGE_PATH(TEXT("eye.gif"))); 
   nRet = MyAnimation.Load(); 
   if (nRet==SUCCESS) 
   { 
      MyAnimation.CreateWnd(hWndParent,0, WS_VISIBLE|WS_CHILD|WS_BORDER,0,0,300,300); 
      //let the even items wait for user input 
      for (i=0; i<MyAnimation.GetCount(); i++) 
      { 
         if (i%2) 
         { 
            nRet = MyAnimation.WaitForUserInput(FALSE,i); 
            if(nRet != SUCCESS) 
               return nRet; 
         } 
         else 
         { 
            nRet = MyAnimation.WaitForUserInput(TRUE,i); 
            if(nRet != SUCCESS) 
               return nRet; 
         } 
      } 
      for (i=0; i<MyAnimation.GetCount(); i++) 
      { 
         L_TCHAR szStr[255]; 
         //get current wait state 
         wsprintf(szStr,TEXT("Bitmap[%d] Wait For User Input?: %s"),i, (MyAnimation.IsWaitingForUserInput(i)?TEXT("YES"):TEXT("NO"))); 
         MessageBox(hWndParent, szStr,TEXT("Example"), MB_OK | MB_ICONINFORMATION); 
      } 
   } 
   else 
      return nRet; 
   return SUCCESS; 
}
